Linear is the answer

For quadratic either the x or y would need to be raised to the 2nd power which they aren’t

Same for exponential ( no variables are raised to any exponent)

The are no brackets representing taking the absolute value of any variable so that can’t be right

You can always test a few values for x to graph the y result to see that in this case it does graph a line

Please help i have been trying to figure this out for like an hour

Answer:

Step-by-step explanation:

Since x varies directly as y, the ratio of x to y remains the same. Let the value of x when y=4 be a. Then we have

$\dfrac {7 \frac12} {10} = \dfrac a4$

We can cross multiply to get that

$10a = 30, \text{so } \boxed{a=3}$

Solve the slope…. pls

Zielflug [23.3K]

Answer:

slope = 5/7

Step-by-step explanation:

Given the x-intercept: (-7, 0) and the y-intecept: (0, 5):

We can use the slope formula:

$m = \frac{y2 - y1}{x2 - x1}$

Let (x1, y1) = (-7, 0)

(x2, y2) = (0, 5)

Plug these values into the slope formula:

$m = \frac{y2 - y1}{x2 - x1} = \frac{5 - 0}{0 - (-7)} = \frac{5}{7}$

Therefore, the slope is 5/7

If = 80°, and m∠BED = 25°, what is ? 55° 30° 65° 20°

Tomtit [17]

The complete question in the attached figure

we know that
The measure of the external angle is the semidifference of the arcs that it covers.
so
m∠BED =(1/2)*[mAC-mBD]-------> solve for mBD
mBD=mAC-2m∠BED
mBD=80-2*25--------> mBD=30°

the answer is
mBD=30°
